On the donation forms and campaigns, you can add an attribution onto the URL like this: ?cf1=XXXX , where XXXX is one word in latin characters.
So, if your donation form is located at https;//securedddonation.com/donate/charity the new would be https;//securedddonation.com/donate/charity?cf1=XXXX
CF stands for "custom field" and it will be attributed to any donation made using this link. It will appear when you export your donation records to Excel through your account.
We support up to 20 custom fields, so you can add up to 20 tracking fields like this: cf1=XXX&cf2=XXXX&cf3=XXXX (etc..)
